Slide Bridge and overpass monitoring FOR STRUCTURAL ENGINEERS Bridge Solutions

Monitoring challenges

Static monitoring

It is necessary to reconstruct the static deformation of the spans to understand the current state of the structure, especially during load tests.

Cost maintenance

Huge structures are very costly to monitor with cabled installations: wireless sensors are the optimal solution.

Dynamic monitoring

It’s necessary to monitor dynamic parameters like oscillations and accelerations to understand the behaviour of the structure.

Surrounding stability

Analyze the deterioration over time of the crucial structural parts of the bridge or overpass.


Using Deck and Accelerometers it is possible to obtain a complete dynamic characterization of the bridge or overpass. Parameters as accelerations, dynamic displacements, modal frequencies and temperatures are constantly monitored.

Tiltmeters allow the analysis of the static of the structure. These sensors, therefore, allow monitoring of the angular variations caused by the subsidence of the ground and/or structural parts. With the use of more tiltmeters inline it is also possible to obtain the static deformation of a span.

With the use of Analog or Digital communication nodes, it is possible to expand this monitoring system with other non-native wireless instruments of geotechnical type.


You can analyse parameters like oscillations and accelerations caused by earthquakes or other anomaly events.

Modal analysis

You can monitor frequencies and natural modes of vibration of the structure.

Static monitoring

You can monitor the static parameters like inclination and the deformation of the deck, settlements, stress, expansion or contraction of cracks and joint displacements.

Vibrations trends

You can view all the trends of the parameters detected by the sensors such as displacement and acceleration.

Bridge IoT remote monitoring

Modal By correlating all the daily oscillations detected by the Accelerometer and DECK sensors, it is possible to analyze the natural modal frequencies of the structure, during a very long time interval.
These frequencies are purged from white noise such as traffic or anomaly heavy loads.

Processing Processing Algorithms Many advanced algorithms and data processing tools facilitate the analysis of the detected data by calculating the average displacement suffered, highlighting anomalous events, understanding the modal frequencies of the structure and much more.

In this way it is possible to obtain and visualize the exact lowering of the span.

Each event is processed with the FFT algorithm (Fast Fourier Transform), used to calculate the frequency response of the oscillations more quickly.
